Page "Hercule Poirot" Paragraph 34

As an adult, Poirot joined the Belgian police force.

Very little mention is made in Christie's work about this part of his life, but in " The Nemean Lion " ( 1939 ) Poirot himself refers to a Belgian case of his in which " a wealthy soap manufacturer poisoned his wife in order to be free to marry his secretary ".

We do not know whether this case resulted in a successful prosecution or not ; moreover, Poirot is not above lying in order to produce a particular effect in the person to whom he is speaking, so this evidence is not reliable.
